Here we once documented a complete rear axle revision based on a BMW E36 rear axle. This axle comes from a BMW E36 320i built in 1996. The rear axles of the E36 models from the 319i to the 320i are the same for all sedans, touring, coupe and convertible vehicles of this series.

From the 320i of the E36 series, the rear axles of the sedans, coupes, convertibles and Tuoring are reinforced. The compact vehicles of this series have their own rear axle construction that only fits these models.

We removed this rear axle from a scrap vehicle at the junkyard and then completely dismantled it for rust removal and also removed the barrel bearings and rubber bearings.

We have planned this axle as a “replacement axle for our BMW E36 318 IS Class 2, because we can prepare it completely and then simply remove the axle and install it again directly.

After 24 years, the axle looks bad in terms of rust on all vehicles of the E36 series if these have not yet been overhauled and protected against rust

Rust as far as the eye can see …

The whole barrel bearings and rubber bearings were then removed …


After 2 days in a citric acid, the E result looks quite acceptable again

The brackets for the brake calipers also look good again, after 2 days all parts were taken out of the tank and steam-blasted and brushed off again with a wire brush and then left in the lemon acid E330 for a further 2 days for gastronomy and the food sector

We also put the brake calipers in the box for fun, although we won’t use them again later, in general we will only use the rear axle body, the two steering arms and the two spring mounts, the rest will be new.

The axle parts of the BMW E36 rear axle were then treated again with Fertan and left to act for 2 days. Then washed off thoroughly with water and, after drying, treated or sealed with BONDEX epoxy.

All small parts are sparkling clean again after clearing and have also been treated with Fertan and sealed with BRUNOX epoxy.
